HENRY B AUSOH, OF ROCHESTER, NEW YORK.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 277,441, dated May 15,1883. Application filed March 29, 1883. (No model.)

To all whom it may concern:

Be it known that I, HENRY BAUSCH, of Rochester, New York, have inventedcertain lmprovementsin Sash-Fasteners, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to an improvement in window-sash fasteners; and itconsists in the combination of parts by which two movable dogs arrangedto slide transversely to each other are arranged so as to lock the lowersash to the side casing while the upper sash is permitted to be closed,as hereinafter more fully described and specified.

My improvements in sash-fasteners are represented in the accompanyingdrawings, in

which-- Figure 1 is a plan' view, showing my improved sash-fastener inthe locked position. Fig. 2 is a plan view, the upper plate beingremoved. Fig. 3 is an elevation. Fig. 4. is a front view of the swingingarm and side dog detached. Fig. 5 is a plan view of the same. Fig. 6is'a side view of the swinging arm and back dog detached. Figs. 7 and 8represent the back dog. Fig. 9 is a plan view of the lower part of thecase. Fig. 10 is a section of the lower case on the line a .90, Fig. 9.

In the accompanying drawings of my im proved sash-fastener, A Brepresent the case; U, the side dog; D, the hack dog; E, the knob on theend of the swinging lever F; G, the arm for operating the back dog; H,the windowcasing or side frame; I, the guidestrip attached to the sideframe; J, the upper rail of the lower window-sash; K, the side rail ofan upper window-sash, and N a metallic strip attached to the side railof the upper sash and provided with recesses to receive the point of theback dog.

The case of my improved sash-fastener is formed of an upper plate, A,anti a lower plate, B, which are fastened together by screws or rivets,and are suitably recessed to receive the operating parts. The front edgeof the upper plate, A, is cut away, as shown in Fig. 3, to permit of theswinging motion of the lever F, as represented by the dotted lines inFig. 2. The case is fastened to the upper side of the upper rail of thelower sash by the screws 0 0, Fig. 1, at one end thereof, in suchposition that the sliding dogs 0 and D may respectivelyengage withsuit-able notches or recesses in the window-frame H and the side rail,K, of the upper Window-sash. The back dog, D, slides in a groove formedforit through the flange at the rear edge of the lower plate, 13, whilethe side dog, 0, slides ina suitable groove formed for it in the upperplate, A. The lever F is pivoted so as to swing freely between the upperand lower plates, being provided with bosses a b, which enter openingsin the plates (1, (see. Fig. 10,) the levers being connected to thedogs, so that they are retracted by its movement. The side dog, 0, isdirectly connected to the lever by the connection L, pivoted at its endsto the dog and lever. The back dog, D, is connected to the lever F bymeans of the arm G, which projects into a recess, h, in the side of theback dog. The recess it permits thenpper window-sash to be moved upward,the back dog yielding inward, as represented by the dotted lines in Fig.6, but being forced outward again by the spring 6, so as to engage inany of the notches in the plate N which may come opposite the back dogwhen the upward motion is stopped. The outer end of the back dog isbeveled from be low upward and outward, as represented in Figs. 6 and 8.The upper window-sash will be held locked in any desired position,either partially open or closed, and at the same time the lower sash isfirmly locked. The spring 6 bears on the inner end of the back dog andforces it constantly outward, and in case both the dogs be retracted, byswinging the lever F it will force both of them outward again, asrepresented in Fig. 1. The catch it drops into the notch o and preventsthe lever F from being moved to unlock the sashes.

It is obvious that a spring or other catch maybe used in place of thegravity-latch n.

1 claim- The combination, in a sash-fastener, of a suitable casing withthe swinging lever F, provided with catch a, the sliding dogs 0 and D,arranged to move transversely to each other, the side dog beingconnected directly to the lever, and the back dog having a recess, h, toreceive the arm G, and spring 6, substantially as and for the purposesset forth.
